When a hierarchy of modes exists (ring-based security), faults and exceptions at one privilege level may destabilize only the higher-numbered privilege levels.

iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in a set of tables, which contain chains of rules for how to treat network traffic packets.

The current standard specifies that missing MEDs are treated as the lowest possible value. Since the current rule may cause different behavior than the vendor interpretations, BGP implementations that used the nonstandard default value have a configuration feature that allows the old or standard rule to be selected. 7: Local to router (Loc-RIB)

The HLA rules describe the responsibilities of federations and the federates that join. [12] Federations shall have an HLA federation object model (FOM), documented in accordance with the HLA object model template (OMT). In a federation, all representation of objects in the FOM shall be in the federates, not in the run-time infrastructure (RTI).
Diagram of a typical network employing DMZ using dual firewalls. The most secure approach, according to Colton Fralick, [4] is to use two firewalls to create a DMZ. The first firewall (also called the "front-end" or "perimeter" [5] firewall) must be configured to allow traffic destined to the DMZ only. The second firewall (also called "back-end ...
